Embodiment 1

[0069] Such as Figure 4 and Figure 5 As shown, a dynamic closed test system for intelligent networked vehicles is proposed, including a straight-line acceleration area, a left-hand turn test area and a right-hand special-shaped dynamic test area;

[0070] The left-turning test area is adapted to be arranged at one end of the linear acceleration area, and the right-handed special-shaped dynamic test area is adapted to be arranged at the other end of the linear acceleration area;

[0071] Compared with the bending direction of the linear acceleration area, the left-turning test area and the bending direction of the right-turning special-shaped dynamic test area are both bent to the same side of the linear acceleration area. ;

[0072] The linear acceleration zone is used to test the speed of the vehicle to a certain range;

[0073] The left turning test area is used to test the vehicle to perform various braking and steering actions to the left after accelerating to a certa...

Embodiment 2

[0095] On the basis of Embodiment 1, a dynamic closed test system for intelligent networked vehicles is further proposed, which also includes a linear acceleration detection module, a leftward 125m test detection module, a leftward 250m test detection module, a leftward 500m test detection module, a right 125m test and detection module, 250m right test and detection module, 500m right test and detection module, linear acceleration safety buffer detection module, safety specification information storage module and intelligent analysis control module;

[0096] The linear acceleration detection module is used to detect the real-time linear acceleration action information of the test vehicle and send it to the intelligent analysis control module;

[0097] The left 125m test detection module is used to detect the real-time left 125m turn test action information of the test vehicle and send it to the intelligent analysis control module;

[0098] The left 250m test detection module i...

Abstract

The invention discloses a dynamic closed test system for an intelligent networked vehicle, which includes a linear acceleration area, a left turn test area, a right special-shaped dynamic test area, and the like. In the present invention, the test vehicle can take the middle linear acceleration track as the core, and continuously perform multiple left and right direction steering and braking tests without blank test time in the middle, which improves the test efficiency; After a single linear acceleration, it is necessary to return to the starting point of the acceleration. The end of each single test is the start of the next test, which saves the test time and saves the energy consumed on the original way back to the field, which improves the test economy; Realize the intensive use of land resources, without causing functional interference to the surrounding test areas / roads, and improve the overall land utilization rate; the number of tests completed per unit time increases, and the return journey of test vehicles is eliminated, reducing exhaust emissions, which is beneficial Improvement of test site environment, etc.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked vehicles, and in particular relates to a dynamic closed test system for intelligent networked vehicles. Background technique [0002] The vehicle dynamic test area is a site facility for vehicle dynamic performance, especially high-speed dynamic performance tests. Multiple vehicles can be accommodated in the site at the same time to carry out tests on mandatory vehicle inspection items such as minimum turning radius, channel circle, vehicle swing value, steering force, etc.; through the effective combination of dynamic square and frequency sweeping test track, equipped with advanced Automatic driving system, high-precision integrated inertial navigation system, and GPS positioning base station to realize precise positioning and control of the vehicle, and it is very convenient to complete the vehicle electronic stability control system and ESC system tests on high-adhesion road surfa...
